Solutions

3 solutions available

1. Verify Wallet State and Syntax easy

Ensure the wallet is open before attempting to close it and that the syntax is correct.

1
Check the current status of the Oracle Wallet. If it's not open, attempting to close it will result in this error.
ALTER SYSTEM SET ENCRYPTION WALLET CLOSE;
2
Confirm that you are using the correct syntax for closing the wallet. The command is straightforward.
ALTER SYSTEM SET ENCRYPTION WALLET CLOSE;
3
If you are unsure if the wallet is open, you can query the `V$ENCRYPTION_WALLET` view.
SELECT WRL_TYPE, STATUS FROM V$ENCRYPTION_WALLET;
4
If the `STATUS` is not 'OPEN', then the wallet is not open and attempting to close it will fail. Open it first if needed.
ALTER SYSTEM SET ENCRYPTION WALLET OPEN IDENTIFIED BY "your_wallet_password";

2. Check Oracle Wallet Configuration Parameters medium

Verify that the wallet is correctly configured and accessible by the database instance.

1
Locate the `sqlnet.ora` file in your Oracle Net configuration directory (typically `$ORACLE_HOME/network/admin` or `$TNS_ADMIN`).
2
Ensure that the `ENCRYPTION_WALLET_LOCATION` parameter is correctly set to the directory where your wallet is stored. If this parameter is missing or incorrect, the database might not be able to properly manage the wallet.
ENCRYPTION_WALLET_LOCATION = "/path/to/your/wallet"
3
Restart the Oracle database instance after making any changes to `sqlnet.ora`. This ensures that the new configuration is loaded.
SHUTDOWN IMMEDIATE;
STARTUP;
4
After restarting, attempt to close the wallet again.
ALTER SYSTEM SET ENCRYPTION WALLET CLOSE;

3. Ensure Proper Oracle Wallet Permissions medium

Verify that the Oracle database process has the necessary read/write permissions to the wallet directory.

1
Identify the operating system user that the Oracle database process is running as (e.g., `oracle`).
2
Determine the full path to your Oracle Wallet directory. This is usually specified in `sqlnet.ora` via `ENCRYPTION_WALLET_LOCATION`.
3
Use operating system commands to ensure the Oracle user has read and write permissions to the wallet directory and its contents. For Linux/Unix:
sudo chown -R oracle:oinstall /path/to/your/wallet
sudo chmod -R 750 /path/to/your/wallet
4
After adjusting permissions, attempt to close the wallet.
ALTER SYSTEM SET ENCRYPTION WALLET CLOSE;
